Working model of a Chevy Camaro LS3 V8 engine.
Over 200 hours of printing!!! Engine block alone was 72 hours.
Modeled from cad files, pictures, specs, and service diagrams of the engine. I did not have the actual engine for this one.
It assembles just like the real thing!!!
https://youtu.be/iAkzb1nXzwU

Also the engine stand will be available for sale soon, if enough people are interested.
It fits my other engines too.

The electric motor that powers it is a 12V 500rpm geared motor.
Shaft Size : 15 x 6mm/0.6" x 0.24" (L*D)
Motor Body Length : 43mm/1.7";Motor Body Diameter : 33mm/1.3";Thread Diameter : 2.5mm/0.1"
The motor housing will need to be filed down slightly to fit the starter mount.

Eric, do you plan on releasing the engine stand?

Mar 26, 2017 - Modified Mar 26, 2017

The flathead and the rotary were at a tie last week so I decided to do the flat head. Next, the rotary.

b

almost done with your first one and its awesome. Cant wait to get this one done!

Mar 26, 2017 - Modified Mar 26, 2017

Very nice. Since it's a flathead it may be a good project for lost PLA casting and making an actual working engine.

will you ever release the files for the engine stand?

Any one else having issue slicing the Exhaust headers? I am getting a few chamber that seem to be solid filled. Also the walls of the headers only seem to slice if i set the layer height to .15 instead of the standard .2 for all other parts.

Make sure you have the most recent files. The old ones had problems printing.

Didn't have a problem printed them at 0.2 using S3D.

I just printed the headers and didn't have an issue. I also could have gotten lucky haha.

hmm you didnt see any issues in slicing them? What slicer did you use?

Cura. 2.3.1 on my ultimaker 2.

Mar 11, 2017 - Modified Mar 11, 2017

Eric, Where do you buy the springs from? I'm creating my own 4-cylinder engine based on General Motors 2.5 liter (151 cid) engine used in most FWD cars made in 1980s. The size of the springs that I need are 7/32" diameter and 11/16" length. The ones from Harbor Freight are too strong.

All the springs are custom made as I was unable to find any that would work properly.

How do you make your own springs?

on a lathe with a mandrel (metal rod) and a custom guide. You can do it on a drill press too, it just takes some trial and error to get a spring that's the right size. You can find youtube videos of how to do it.

I'm printing the engine block now and I'm so stoked to get it put together and I'm not even close too having all parts done.

Awsome design mate.

I need a bigger printer! This model is awesome. Looking forward to building one down the road with I have resources up to the task.

any chance for a S70B56?? :)

rocker_arm_pin_scaled.stl is dropping on teh build plate in S3D with a dimension of X:158.06 Y:158.06 Z:225.81mm for some reason. All other thus far have been fine.

What are the dimensions of the pin so I can scale it back down and print it out?

Thanks,

Planning on using this for a school project, contact me at [email protected] as I have some important questions

Will this work in my G-Wiz?

Any chance I could get these files as .sldprt files rather than .stl? It would be greatly appreciated.

Come on guys vote 2jz!

Please help me decide which engine to do next..
I'm leaning towards the Porsche Four cam, but would like to get some input.
Keep in mind that the inline 6 cylinders will most likely
not be able to be printed in one piece on most printers.

Personally, the Harley or Ford would be great. Where does one come across the blueprints to model something like this? I would love to model some engines in Solidworks.

Pretty awesome ! Love it, will be my first print on my printer im ordering month end which is next week heheheh !! thumbs up x10000

is it the same scale as the other engines?

how much filament does this model use?

I was wondering if anyone else was having issues with the cam gear and the crankshaft gear alignment? I've assembled the crankshaft and the camshaft per the assembly instructions, but when installed into the block the cam gear is much further out of the block than the crank gear.

Both first bearing journals (closest to the timing cover) are essentially in the same plane in the block, but the distance from the timing gears to the first bearing on the crank and the cam are very different.

Are all the cam lobes lined up with their corresponding lifter holes? That's the most important. Make sure to check your dimensions of the assembled camshaft also.

Yep, measurements are good, sighted down the lifter holes and the corresponding lobes are below. The gear on the camshaft sits about a quarter inch further out from the first bearing than the crank gear does.

Let me see if I can put the pictures somewhere I can link them.

Looking straight down, camshaft is in alignment with lifter bores.
pic3

After reprinting and rebuilding the camshaft for the third time and meticulously measuring the distances, the only solution I found was to grind down he surfaces between the cam gear and the "cam bearing surface 2". Now the cam gear is in alignment and so are the cam lobes.

Am i missing something? How does the valve covers attach to the heads? I see holes for magnets on the valve covers, but nothing on the heads. Anyone else run into this issue?

Feb 8, 2017 - Modified Feb 8, 2017

No magnets on the valve covers, just four SHCS that locate it on top of the head. It's just held on by gravity. The 4 screws just keep it centered on the head, nothing more.

Any plans to do more parts for this motor like you have the Toyota? Tranny, Drive line, rear end stuff like that.... also if you get bored would love to see a 6.6 Duramax

Here is the Air Intake I printed with Cura added supports. I think the Filament was bad as it performed very poorly. I switched to different filament for the engine block and that came out great.

Is everyone else printing the air intake with support like I did. I tried without support but the Flange where air filter bolts to wouldnt print correctly due to the large overhang. So I added supports with Cura and it came out as shown.

Printed at .2 layer height.

Any one have better success wit hair intake? Please share any helpful info and or settings that I can adjust to get a better result.

Looks good to me. I'll mess around with the intake and put support under the small section where the throttle body mounts. When I print it, I just let it print in mid air in that section and then just trim it off when it's done.

what kind of filaments are you using for the parts

The Black Filament used for the Air Intake was Straight from ultimaker PLA. It didn't seem to work well at all. I will get new Black PLA and see if next print is better.

I Printed the Engine block with Eric's Built in supports, layer at .2, 20% Infill Grid, print speee 60 mmm/s, Cooling Fan at 55% after 3 layer. It took approx 80 hours. There was a little stringing on the sides where parts overhang 90 deg. I think turning the fan to 100% would help with this and cool the material coming out faster preventing less droop and stringing. Other than that, it look absolutely amazing. Thanks for posting and supporting this Eric.

Can you contact me on how much this would cost, I dont have a printer.

Possibly about $12.00 in ABS Fillament but at least two weeks of printing and maybe 10 hours assembly plus extras. Some where between $200.00 - $500.00 Cheers Jace

About $60 from JUST the filament. hundreds from online printers.

Can you contact me on how much this would cost, I dont have a printer.

Printing the second cylinder head now, planning on printing the engine block over the weekend. The detail is fantastic. I printed the heads at .1mm layer height, but am going to shift over to .2mm layer for the block. Cura estimated a little over 2 days.

I want this. I don't have a printer. Can you contact me with a price on a complete package. All the pieces and parts.

Aawsum thank you for another great engine model eric. I have printed the 22re for myself. And i am also printing the camaro for a friend. I have 2 suggestions for you for engines for this year thats if you are up for it. Toyota lexus v8 and a toyota 7mge that would be nice

One thing is for sure.... The HARDWARE KITS Eric sells are absolutely worth it. Well beyond my expectations. I was looking on Amazon for magnets, an to my surprise, those where included also. I paid the money and got the DC Motor, Speed Control and power supply. Worth every penny. The kits come in a nice little hard case. All parts are in small baggies and labeled including magnets, push rods, springs, and bearings. Im stoked on the attention to detail. I imagine the parts could be found cheaper, but having a complete set up as finally packaged as the ones from Eric seem to be worth every penny and certainly worth no having the worries of not getting something right on your own. Way to go Eric, I was not expecting these to be so sweet. I can only imagine what the stands will be like when they arrive :) Thanks again.

Pics of Parts Kits exactly as it arrived from Eric

Looking great!! Already planned on getting this kit from eric when all print work is done, now i'm certain of it!

For my first one, I did the McMaster thing, and you end up with tons of extra this and that. OK if you're going to build a bunch of them over time, or you just so happen to like M3 screws and nuts. So yah, the hardware kit is well worth it.

Can I buy the whole kit from you if I don't have a 3d printer?

I had asked Eric if it would be ok if I produce printed parts kits for this. Last we left it was for me to actually print a set and figure out my costs and asking price.

I believe Eric has plans of his own to build a print farm to be able to print these, but he can speak to that himself.

If there's interest, you should send Eric a message. If there's tons more than he's willing to do on his own, I can jump in and provide kits of printed parts. I have a rack of printers, so each kit takes about as long as the longest part to print, which is roughly 3 days.

does anybody know how long to cut the push rods?

The length of the push rods depends on so many different factors. the best way to figure out the length is to cut one to the length stated in the parts list and install it. Making sure that the cam timing is perfect and that there is no binding anywhere else. If the the head lifts while rotating the motor then the push rod is too long. Shorten it in half mm increments.

Think you could make a powerstroke?

Hi Eric,

Do you post the hardware kits internationally? I live in NSW Australia

Yes, shipping internationally would be $25 for one complete kit.

Hi Eric,
I have the monoprice clone of the Prusa I3 printer that you specified in the print settings. After Cura slices either the engine blocks with and without supports the estimated time is 5 days and 9 hours. How did you get your printer to do it in 72 hours? And did it print better with or without supports?

I printed the engine block 20% fill on a MakerGear M2 in 28 hours in solutech silver pla (Amazon). It looks incredible. This is the file with supports, I did not add any supports, but if printing again, I would manually add supports only under the large outside horizontal ribs (4 plcs) and in the center of the camshaft bore ends (2plcs). Everything else printed perfectly. This is far and away the most incredible thing that has ever come off my printer. Thank you for sharing.

What are your speed and infill settings?

60mm/s and 50% infill

cut it down to %20 infill. I printed the engine block at 50mm/s, 20% infill.

I am getting a estimated build time of 6 days. Using Cura Ultimaker 2+ .4 nozzle.

I have support set at 63 deg overhang, zig zag, density at 15%.

Print speed is 60mm/s, infill density 20%, layer height .1mm

We need to print with support right?

Any tips or reasons why mine is 6 days or how to get it done in less time?

Jan 26, 2017 - Modified Jan 26, 2017
ericthepoolboy - in reply to patrick28x

print stl file with built in support. No added supports unless you can add them manually with your slicer.
Layer height of .2mm should be sufficient.

with or without supports?

I would print the STL that has built in supports for the mains only.

I love this design! Estoy fabricando todas las partes del motor para luego montarlo. Se tarda bastante en hacerlo pero es impresionante el diseño y los detalles. He fabricado también un soporte en acero para sostenerlo. Buen aporte. Un saludo

How do you guys print the piston heads? Do you print it upside down with top down onto print bed? If so, do you use supports? I was going to do this but thought support would take away smooth finish where the recess is in top of head? Any tips or pics how you print and support settings would be appreciated.

i printed mine just as is in the STL file, with the face that mates with the block down. This side needs to be very smooth to mate with the block properly.

Hi Eric,
Thanks for the response. However the drivers side valve cover is still to small. The passengers side seems as though it is the correct size but the other is not. Am I the only one who has this issue? if you load both valve covers the drivers side is not the right size. Please let me know

Try the newest files. No idea why the old ones were scaled like that.

ok I took the parts and dragged them onto my Z18 build plate and the size of the engine block and the heads look ok. But the passenger and drivers valve covers are completely different sizes. Is anyone noticing this also?

Ok I really need someone's help. I am 20 hours into a 48 hour engine print and this engine does not look the correct size. I have already printed out the drivers and passengers side valve covers and one is much larger that the other. Can someone send me some updated files, as I really feel something is wrong. Please help.

The valve cover files are updated as of yesterday. Not sure how the old file got resized.

Hi Eric ,

I would be interested in the engine stand if you decide to make them. Also i cant thank you enough for this model and the hardware kit was a great investment .

I would also like a stand, or the plans to build one would be good too

Eric,
I just printed out both the Drivers side and Passengers side valve covers; however the one side (Drivers side) is much smaller than the other side. I didn't change the files I just printed them as they were. I'd Appreciate any help. Thanks

There was an old file for the valve cover that never got deleted, not sure why it's a different size though. Download the most current files.

I remember the old Revel visible V8 kit, that thing was great! now i can print this with the heads and block made from clear ABS and give it an acetone bath maybe? VERY cool project. I will look forward to printing this model and making it later when i'm more experienced.

so where is the video?

click on the second picture

I'm having trouble printing the valve covers. no matter what slicer I use, I always come up with square holes in the cover right above the bottom lip. Has anyone had a similar problem? One of the covers has three holes and the other comes up with one in the center.

I had a similar issue when printing my smaller scale version. I made that wall a little thicker in my remix http://www.thingiverse.com/thing:1996991 . If you use them just be sure to scale them 200% since mine is half scale.

Smaller LS3 V8 Engine - Working Model

I sent Eric an email, and while eagerly awaiting a response, I'll scale up your remix and see how it goes. Thanks, Novel!

Updated with a thicker wall. The old one slices fine for me in cura, with a .4mm nozzle setting

Eric,

I was having the same problem with the valve covers (even with Cura and .4mm settings). Anyway, thank you for uploading the passenger side it looks like it will work! However, I get three holes on the drivers side, can you update and upload that file? I appreciate all the hard work, you have made some unbelievable models here. It has inspired me to do one of my own.... I will upload to Thingiverse when I'm complete, I really understand now the time it has taken you. I have completed a design on an engine stand, when I get the build complete I will upload the design and pictures.
Thanks!

Would it be possible for you to upload the step files? Using this for a school project, thanks.

I formed a support group for anybody that has questions about printing and assembling my engines.
http://www.thingiverse.com/groups/3d-printed-engine-support-group/topics

Update the exhaust manifolds/headers. Should print better than the old ones.

I can confirm they print well Eric. Thank you for repairing the files.

Updated, I guess i forgot to save when I uploaded them.

Hi all ,

 If you plan on printing and building this project i highly suggest buying the hardware kit from Eric .

This kit has every nut , bolt and screw you will need , i had him include in my kit the motor , control board and power supply .
This is well worth every penny , everything is bagged and tagged , first class all the way. Just waiting on filament for the block.

Thank You , Eric

can anybody point me to where to get the 3mm wide timing belt? I just assumed it was the same as the belt I had leftover from the subaru engine. It is not.

Aliexpress has most things

Happy new year everybody :P

Here's a pic of my latest print. Oh yeah, it failed. Again.
smile

And it's stuck to the print bed. Again.

Luckily i now can replace the bed in about 5 minutes, so the glass bed is in the freezer now. (gotta be carefull with that one to get it off later.)

I've got my other laptop here now so i hope that will allow me to use S3D to run the printer.

How do you add the pictures in the post? I want to share too :)

exclamation mark, [smile] and then the url of the jpg within ()

What is the minimum bed size to print this? Will a lulzbot mini do it?

Some parts, like the engine block, are big. 161x182x112mm. So that won't go in your printer.

You could of course, like some others have done, scale it down so it fits, and make it a static model. Check the remixes some have made. There's also a working model that's scaled down :)

This just happened.

Could not get my print off. Have taken out my bed and it's in the fridge now, hoping that will help to get it loose. At least now i can also install my glass bed, which i had since i bought the printer just never felt like installing it.

It looks really good though :p

Had it in the freezer for a couple of hours, still had to use a couple of pretty hard whacks with a hammer to free it from the printbed O.O I was afraid to break it but it's rock solid :D

It came out pretty well, have a look for yourself:

In some pics it looks kind of warped but it is not. Just an effect from the close up i guess. I printed this on a XYZ Da Vinci Pro 1.0, with Real Filaments Satin Silver PLA on .2 with 20% infill on 210 degrees celsius and bed on 60.

@ericthepoolboy, any suggestions for the clean up?

I got tired of larger prints sticking to the bed, so on advice I found from another build on this site, I forked out ~$10 for a Japanese Spatula (actually, this one from Amazon: https://www.amazon.com/gp/product/B000WG14FC/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1).

It works wonders... catch an edge, twist, and Pop! off it comes. Best part is that the spatula doesn't mar the board surface, which you risk with larger tools (like chisels).

One of those is an absolute necessity. They work great when printing on any surface. They can also be found under "3D Print Removal Tool" on amazon. I also use a small drywall taping knife for larger prints. I print with a brim and just give it a good smack on one of the corners.

I use a set of small wood carving chisels. They have a nice sharp tip and they have many different contours so you can get into just about anywhere. I use a small hot air blower set to about 190 C to hit the surface after wards to make the surface color uniform.

I want to buy one!!!!!
(don't have a 3-D printer)
amazing
i also want to buy all the other things you've designed!
Keep it up!!!

Crazy!! Thaks for sharing this amazing project!

This is awesome! Definitely will be getting one....can or would you do other motors? Like possibly an h22a4?

For those who don't have holes in some of the prints, check if you've got something like "merge all outlines into a single solid model' option on. This has to be disabled.

Besides that, i'm having my printer run 24/7 haha, now printing the engine block (with supports) on 0,2, 20% infill. Installed a fresh printhead for the job as i've printed a lot of bronze/copper/alu filaments with my old one, wanted to be sure to get the best results. I'm using REAL PLA SATIN SILVER for the 'aluminium' engine parts. The engine block is about 1/5th done, looks really nice with this filament, so i might be doing the valve covers en rocker arms and pins again in the same filament. It seems to be a bit smoother then the ABS/PLA's i've used so far so this might cut down on post processing time, but most importantly, it looks awesome :)

smile
I just made this picture and it has warped :( Now i'm in doubt whether i should continue or cancel the print.

As it's the underside of the block, and backside of the engine, i think it'll work out. The only thing that needs to be attached to the bottom would be the oil pan.

Edit2:
Well i guess it doesn't matter anymore now :(

Well dont give up , just keep in mind how much work Eric invested.I am having just as much enjoyment printing this as i am building my LS3 427 stroker

Give up?? NEVERRR!!! ;) I started printing the cylinder heads now, waiting for more filament to come in :) Wasn't sure there was enough left on the reel.

Dec 24, 2016 - Modified Dec 24, 2016

Thanks for all the great models. I am printing this now and I have found that the exhaust headers have some issues. From what I can see the walls of the parts that are thin walled are less than 0.5mm thick (can't print at full scale never mind smaller). Also parts of the headers are solids not thin walled. Thanks again for the amazing models.

EDIT: Also I just noticed that the intake is not sitting flat on the build surface. It looks to be tilted at 1.3 degrees (front is up).
EDIT 2: Now that I am printing the final parts I keep running into issues. The current issue is the rockers do not have a hole in the bottom to allow the bolt to go into the rocker rail. You also mention removing support from them but there does not appear to be any built in support and until there is a hole in the bottom I can not see them needing support.

Yes exactly. Left exhaust header has 2 pipes solid, right does have one solid pipe. Repairing in netfabb didn't help.

Intake manifold has been repaired already, re-download the repaired version unless you can lay-flat it.

Rocker arms doesn't have the hole, which I just realised after printing all 16 (17) of them :) And yes, even I was wondering why should I use support as mentioned in pdf. :)

You can see what it's supposed to look like. Here is the underside of an actual rocker arm.
http://www.coloradospeed.com/images/colorado_speed/CS10214664_C.jpg

Access forbiden.

The support material for the rocker arms needs to be removed with a razor blade to separate the layers. On the underside of the rocker you'll see two narrow slots. Remove the material between. There should be a square hole. The exhuast manifolds print fine in Cura. I'll look at them later and see about modifying them.

Something like this? Because there is no hole in the actall stl file. Bottom side is solid and thus there is no need for support as stated in comment above. Sorry if Iam missing something. :)

Yes, there should be two gaps on the vertical wall. All material between the gaps should be removed. Look at the rocker arm in the thingiverse viewer. It shows the gap. Some slicers might not recognize it as a gap and just skip over it.

Deim - in reply to ericthepoolboy

Now I do understand what do you mean. I will try it on my rocker arms, but I doubt it will get delaminated without braking, since there is no interface layers like on the real support matterial. I suppose you could increase the distances between the actual part and the support, so razor blade delaminates exactly the layer you want to. Or actualy leave it blank and print with real support and just file the hole square. I don't know, but this way it is "complicated. :)

I tried to design this part with support and without support. With support designed in to the part, my slicer did not proper print it. Printing the part without built in support and allowing the slicer to add support, caused more problems also. The size of the hole needs to be the same as the mounting surface on the rocker rail, printing with support will cause that distance to be smaller and it also cause the first couple layers of the inner circle to not print properly. I will upload a part file without support later, but printing the current part and using a razor blade to break off the "support" is what i found to work best. It probably wont break off at the exact layer but you would just use the razor blade to cut off the layers.

Eric could you repair the exhaust manifold files?

I made new ones. I'm test printing them now.

Eric, did you manage to fix the EXHAUST manifolds? I would like to print them. :)

New ones are uploaded. They are names LS3 Header. The old ones are deleted. The wall are 1.2mm thick so either printing with a .4mm nozzle or enabling thin wall detection would be wise. Print with support touching buildplate and support for anything other 75 degree angle.

4age coming soon?

If someone has one laying around that the want to give me to reverse engineer.

You are the man! Thanks for uploading a split version of the engine block. I am still going to try to squeeze it onto my Flashforge Creator Pro with the new glass bed upgrade that I did. http://www.thingiverse.com/thing:1127638 I just printed the corners and installed the bed last night and it makes use of the full travel of the x and y axes. Definitely recommend for anyone with a Flashforge, now to see if I can fit this block on there...

Extended Glass Mount for Flashforge Creator Pro

this is amazing!!!! I really want to print one, but my print bed is only 8x8x7. i have checked most of the parts, but is there any print i would not be able to print?

Amazing work. Loved watching the video!

I reaaalllllly love this 'thing', thing of beauty if you ask me :P

However, i've tried to start the print, and i've started the intake manifold multiple times already, but everytime it fails miserably. It starts with a small piece but in the end my whole extruder is clogged up from the outside with a 4cm diameter plastic ball :S

Any idea why this is happening? After i've cleaned it up again, print anything else, everything works perfectly with smooth prints as a result.

nvm, just found the same as the post below :P

@ericthepoolboy: Eric, please, rotate the Intake manifold so it lays flat. P.M.

Also, Oil pan is not laying flat as well. There is some rectangle which is 0.1mm lower than perimeter of the pan.

I thought I had fixed those. I'll fix them and upload new files later today. But if you can't wait, some slicer have a "lay flat" option under the rotate option. I know cura does.

Eric I know. Thing is I slice these in new standalone Slic3er Prusa edition which has this new "ensure vertical thickness" option. This option helps to provent "holes" on vertical surfaces (oil pan, intake manifold etc.). This standalone Slic3r doesn't have "lay flat option" like Repetier host which I use on standart basis. Thanks for you attention :)

updated the files

I just started to print the updated version of intake manifold. On the header, there is a place which is entirely in the "air" and thus cannot be printed without support (as stated in pdf). If possible, fix the shape of the intake header or place some "hardcoded" support pillar under it.

had that problem also, but there is a lay flat option in my slicer that solved it.

I want to build a special engine using alternative fuel and need assistance with the engineering. If anyone wants to know more about the project or wants to help, reply to this message.

Dec 20, 2016 - Modified Dec 20, 2016

Hareware kits are available. $52 for all the fasteners, bearings, rods, springs, and the belt. Fasteners and rods will have to be cut to length as indicated in the parts list. I also have the 500 rpm motors for $17, speed controller for $6, 12v power supply for $4. Everything should all fit in a flat rate envelope so $6.95 for shipping in the US. I'm still working on setting up a website to sell them but you can PayPal me at [email protected]

Is it possible for me to buy the springs and the belt only?

Yes, $20 shipped in the US for the belt and 16 springs.

How much is shipping (for just the hardware kit) to the UK mate?

EDIT - Also are you doing hardware kits for your other designs?

I believe priority shipping to the UK would be $35. I will be selling kits for my other models as well. The Subaru kit will be priced at $50. Just waiting on more parts right but shouldn't be too long.

Cool. I'll be in touch in the new year.

By the way is there no other shipping alternative to the UK?

Dec 27, 2016 - Modified Dec 27, 2016
ericthepoolboy - in reply to wywywywy

I wish there was. I don't think there is a cheaper alternative but I will keep looking as I would like to offer this kit to as many people as possible and shipping from the US to other countries is always expensive.

Update: so First class international is $22 for 2lbs. The kit for this engine with motor and speed controller is just under 2lbs. Shipping for 2 kits (4 lbs) would be $34.

I forgot to ask one more thing - does the power supply work with 230V as well?

Yes, but it has a US plug on it.

I have a Monoprice Select Mini printer, which has a very small build volume. I'd have to slice the engine block into 4 parts if I wanted to print it full scale on my printer.

Do you think I'd be able to assemble this at 0.6 scale? I'm guessing I could go down to M2 screws instead of M3 for most of the project, but I'm not sure if I'll be able to find scaled-down versions of the other hardware parts.

Got any thoughts on this wacky idea of mine?

Is your hardware kit complete including the motor, timing belt etc? I would like to buy one from you to complete this build.

Thanks

The kit I have received from him includes the timing belt, but you can purchase the motor, ESC, and psu from him separately. I've got my kit now, he has it packaged in a stack-on plastic compartment organizer. Pretty awesome to have the organizer too.

This is the message he has posted above and elsewhere -

I noticed after the original post. I have a hardware kit plus everything else that should be arriving today! Thanks.

what motor did you use for the movement of the engine?

doesnt the camaro have the lt engine?

Comments deleted.

I have a 2014 Camaro SS 1LE with the LS3. 2010-2015 have the LS3 (manual trans) and L99 (automatic trans) and LSA (ZL1). The 2016 Camaros have the LT engine series.

It depends what year and kind of camaro, for example a 98 ss camaro has an ls engine.

This is amazing! I have been waiting for a quality v8 to print! I do have one request, Is there any way that you could somehow split the block into a glue together 2 piece design? I am using a flashforge creator pro and the block is just a hair too big for me to print :(

Can't you just scale it down like in cura

Dec 20, 2016 - Modified Dec 20, 2016

Id rather not scale it down because I plan on assembling the whole model and the hardware, bearings, motor etc. would no longer work. I think I will go the route of printing in two pieces

Use meshmixer. It is free and works well. Here is a guide on how to split.

It depends on the program you use to put the design into code for the printer but you could slide half of the design out of the virtual plate so it doesn't print that part and then later flip it so the other half is out.

I downloaded the trial version of Netfabb and I am able to section cut and save it out as two different stls. The bummer is theres really no awesome spot to split it without going right through the cylinder bores or main journals.... we will see how it goes when I get more silver filament. Right now I'm printing the intake manifold, so far so good except for the lower right of the throttle body flange. It says print with no support, but I did notice that that is impossible to do properly without a support under that part

Yes, there's one little spot on the intake manifold that prints in air but you can just trim that little piece later. If you printed with support on most slicers it would put support everywhere you don't want it.

That's nuts! Nice job! I don't think my rep rap would last a 72 hour print!

Any interest in selling an assembled unit? Or a complete kit to build up?

WOW! This is amazing! As someone who regularly builds LS engines, I gotta say you did an amazing job with accuracy!

But now you've got me thinking, wonder how much compression the Taulman 910 could handle with this build, Couple 3D printed piston rings, and a mist spray system and this could be a TRULY working model. :D

Matti Holtzberg - Polimotor... you might find that interesting :-)

Good Job Eric made it on the main page

If you've got the time, you should make an 4 rotor.

Please make the f20c honda!

This is awesome, thank you for sharing all your hard work

This is awesome, thank you for sharing all your hard work

This is perfection. I wouldn't be surprised to see you come up with an entirely different way to build an internal combustion engine, drawing on your experience from the other work you've done.

could you post a video of you putting the cam shaft and crank shaft together we are building this for a school project

I don't have a video of the assembly process for either. The drawings show how they go together. I used an Epoxy to assemble the camshaft in sections, making sure each piece was properly aligned and at the right distance before the epoxy set. The crankshaft was assembled without epoxy and test fitted with all the mains tightened down and the pistons installed to make sure there was no interference. the disassembled, glued and reassemble, and re test fitted.

Once again Eric proves he is Da Man .... Da Motor Modeling Man

Toyota motors and transmissions, Chevy V-8s ,,,,,, Cripes I'm going to have all 3 of my printers working 16 hour shifts from now until June ......

awesome printing one now

Contact me with a link or something I can use to purchase the kit from you, will be building motor within a week. A rough price would be great, I live in bemidji MN

Very cool! Do you think it would be possible to forge the parts out of aluminum and make an actual working engine?

You can do lost PLA casting. I just don't have a foundry. If anybody is up to the challenge though...

This is something I would love to see :D
from print to working metal.... that would be something very cool.

Amazing work! I'm curious about your process of designing the moving parts. Do you make a lot of trial prints of portions of the engine to test fit and function? How did you find the right amount of clearance to give parts so they don't bind up (the pistons in the cylinders, for instance)?

Everything is designed in CAD as one assembly. Clearances are just standardized now from all my past motors and transmissions. Most parts are only printed once if you can believe that.

LS power! Nice job. Cammed LS1 in an 02 SS over here..405whp

That is absolutely fantastic. Great job...

If I may ask, approximately what scale is this engine? I'd love to print it as a non-working model for use in 1/24 and 1/25 scale model cars and trucks. I love your work! All of your engines and transmissions are beautiful. There wouldn't happen to be a transmission to back this masterpiece in the works would there? Thank you!

Hmm, not a bad idea. I have many 1/24's that could use this. Let me know how it turns out. And of course, if you make it work, toss me the STL's, lol.

how big is the engine block (Length by width by height)

Looks like the version in the stl files for the block are right just under
x-161mm y-182mm z-112mm

Is it possible to get one of the hardware kits all the way to new zealand? if so how much will it cost?

I'm working on getting more materials from suppliers but right now the kits will probably be priced at $52 US. That includes all the bearings, fasteners, springs, belt, and magnets. You will need to cut and grind the rods/fasteners to size as noted in the parts list.
I have the DC motors and soon the speed controllers available for $17 for the motor and $6 for the speed controller.
Just from looking at the post office website, shipping would be $35 for a small flat rate priority box to New Zealand..

I am interested in the kit including the motor and controller. Can you Payhpal invoice me for the total cost @ [email protected]?? Great work.

Does it fit the trans?

No, but if somebody has a tremec 6 speed laying around or the CAD files, I can add it to the list.

What exactly would you need to do a tremec or 4L80? There are half a dozen of each at my shop at any given moment, not to mention a hundred other engine/trans combos from the early 1900's up Figured maybe I could lend a hand.

Thinking of printing these in a non-functioning smaller scale (no internals) to give to some of my customers. I've done probably 16 or so LS swaps this year, and 3 Z06 supercharged LT4 swaps, some of them in half million dollar+ cars. Figured it would be a good gesture to my customers.

Ideally I would like the whole transmission. I'm not sure i would attempt an automatic transmission at this time just due to the how they work with fluid and the clutches and planetary gears are hidden anyways. Wouldn't mind doing a flathead V8 in the future....

If you were closer I could provide you with all sorts of stuff for modeling. I work at one of the biggest auto restoration shops in the country (if you watch the Velocity channel, you might have seen me / my shop) unfortunately shipping a trans cross country to be pulled apart for modeling just isn't an option. I'd like to see a flathead done too, and I happen to have an old flathead Cadi rotting away behind the shop.

So you work for Fantomworks? That '65 C10 build was pretty badass. I'm building a 66 at the moment.

Where do you get the screws to assemble the engine?

I buy in bulk and in a large assortment as I don't know what size screw I need till after I model everything. I will be selling complete hardware kits for all my models shortly.

I personally get everything from McMaster Carr here in the states. Been buying their hardware for RC and other projects for ten plus years.

And here I am almost finished with the EJ205......

This is now added as well. I am glad I bought so much hardware for the first engine. I might have some similar bearings and nuts to use now!!!

That engine stand though, NEED that!

Yeah, the engine stand is what makes it look great. I chuckled a little when I mounted the V8 to it for the first time just because of how realistic it made it look. I'm working on getting prices for materials and some laser cut parts for it right now.

Oooh, metal too!!!! Hmmmm. I was wondering how that could be printed and strong - can't.....

Yeah, metal. All welded up. I tried to figure out a way to make it printable but it just wasn't practical since the engine ways a good 5 pounds and that much weight cantilevering off a printed part would be disastrous.

looks like the rocker arms need to be modified because there is no hole for where the m3 screw goes thru the bottom portion on the arm to secure to the head

The material that you see on the rocker arm needs to be removed after printing, Trying to print support in that small of a section would prove to be difficult.

awesome job. what printer and size print bed did you use

220mm x 220mm x200mm

Please let me know as soon as you have the hardware kits available, I would like to buy one. Thank you!

I'll work on a total later today. Still waiting on some parts.

Please let me know as well. Might have a few holiday dollars left to put towards a hardware kit.

Thank you, I am also interested in the engine stand, just add me to the list!

Outstanding! I can't wait till I have the time to print this! Do you have instructions on how to make the engine stand?

I don't at the moment. I was planning on possibly selling them. Making only one of them is a pain. I'm getting together material prices and laser cut pieces for it right now.

Also I'm having trouble finding valve springs. Where did you get them? Or make them?

Comments deleted.

I was going to print the engine but I found out that the engine block is too big for my 3D printer. Its build volume is 235 mm X 145 mm X 150 mm. I could use Netfabb to cut the engine block in half lengthwise, print both parts, and cement the parts together but I'm not sure if this will work. Any suggestions?

You could possibly cut it in half but the cam is held in place by a "press fit". So if you glue it together then the cam might split it apart if the fit is too tight or it my slide around if its too loose. I'll take a look at the block and see if there anyway I can modify it to cut it in half and have it screw together instead of gluing.

Status on modified engine block?

Cutting it in half and attaching it with screws doesn't look like it would be practical. The holes and fasteners would end up in weird location. Your best bet it to cut it down the middle, print, then flat sand gluing surface, and use a quality super glue. Should be string enough considering the surface area to be glued.

And made TO SCALE!? Damn.. you da man, Eric.

I'm Impressed, and the Engine Stand, I love it.

Very nice! But too nice for my notebook... :D I think it will be impossible to print it, cause this mine s**tbook can't even run the visualisation of sliced block :D
